Can olive oil melt away fatty liver? new study investigates
NCT ID NCT07412444
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether adding extra virgin olive oil to the diet can improve liver fat, inflammation, and blood sugar in people with MASLD (fatty liver disease) who are overweight. Researchers will give 60 participants either 3 or 9 tablespoons of olive oil daily for a period, then measure changes in liver fat using a special ultrasound-like scan and blood tests. The goal is to find the best amount of olive oil to help manage this common liver condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- extra virgin olive oil
- What this could lead to
- If it works, this could show that adding more olive oil to a Mediterranean diet helps reduce liver fat and improve metabolic health in people with MASLD.
- What could go wrong
- This is a small, early-stage study with only 60 participants, so results may not apply to everyone. The higher dose (9 tablespoons) adds many calories, which could offset benefits.
